Spare base pate / flange / adapter for GSO refractor focusers. Should fit all GSO 86.4mm and 96.6mm Crayford, Linear Bearing or R&P refractor focusers that have a diameter of 73.5mm (2.89") on the inside of the focuser body. Before purchase, please remove the current base plate on your telescope and carefully measure the inside diameter of the focuser body to ensure the opening size.
Please note that this item will NOT work with GSO's 112.5mm refractor focusers, reflector, RC or SCT focusers or with any other non-GSO focuser. The design of the focuser body at the end where it connects to other adapters/base plates is not standard across the GSO focuser line, so they are not interchangeable. Meant only for use with GSO's refractor focusers that come with an 86.4mm or 96.6mm diameter flange.
To change the base plate on your GSO refractor focuser, simply remove the rotation lock screw, unscrew the 3 holding set screws, remove the old base plate, and attach the new base plate in its place. This requires a 2mm or 5/64" allen key (not included). Note that you will have to carefully adjust the tension on the set screws to ensure that the new base plate is smoothly rotatable. We also strongly recommend the use of removable (Blue) Loc-Tite to lock the set screws in place.
Weight = 5.1oz.; Telescope side outside diameter = 86.4mm (3.40"); Focuser side outside diameter = 73.5mm (2.89"); Total length = 40.5mm (1.59").
